This is probably better placed in support/dependencies, using the
suitable-host-package infrastructure. Put the PYTHON2 script in
support/dependencies/check-host-python2.sh, and create a
support/dependencies/check-host-python2.mk containing:
PYTHON2 := python python2
PYTHON2 := $(call suitable-host-package,$(PYTHON2))
ifeq ($(PYTHON2),$(HOST_DIR)/usr/bin/python)
HOST_PYTHON2 = host-python
endif
Actually, maybe DEP_PYTHON2 is a better name for the dependency. Or
NEEDS_PYTHON2.
Regards,
Arnout
